The double 85 temperature humidity test chamber is widely used for product testing in various fields such as electronics, electrical appliances, mobile phones, communications, instruments, vehicles, plastic products, metals, food, chemistry, building materials, medical, aerospace, etc. For example:

• •Electronic semiconductor industry: used to test the performance and stability of electronic components and equipment under different temperature and humidity conditions, such as chips, mobile phones, computers, and other consumer electronics products.
• •Materials Science: Used to evaluate the physical and chemical properties of materials, especially polymers, coatings, composite materials, etc., in high humidity and high temperature environments.
• •Automotive industry: used to test the durability and reliability of automotive components and vehicles under different climatic conditions.

The testing standards for double 85 temperature humidity test chambers usually vary depending on the industry and product. The following are some common standards and specifications:

• •ISO 16750: The International Organization for Standardization (ISO) standards for automotive electronic equipment include testing requirements for environmental conditions.
• •MIL-STD-810: The military standards developed by the US Department of Defense cover various methods of environmental testing, including high temperature and high humidity testing.
• •IEC 60068-2-1 Environmental testing - Part 2: Test methods - Test A: Low temperature specifies the methods and requirements for low temperature testing.
• •ASTM D 2247： The American Society for Testing and Materials (ASTM) standard involves testing the performance of coatings in high humidity environments. The double 85 temperature humidity test chambers also complies with testing standards such as IEC 60068, ANSI/TIA/EIA 455-162,  BS EN 61300-2-48, JIS Z 0202, etc.

The control system of the Sanwood test chamber adopts the world's leading software and hardware system to ensure that the test chamber operates under preset conditions, provide accurate and reliable experimental data, and help users achieve precise control and data collection of various experimental conditions.

• •Controller: It adopts the controller imported from South Korea Sanwon and the self-developed control system, which can be equipped with Siemens control system and equipped with RS232, RS485 and Ethernet communication ports.
• •Programmable control: It supports setting experimental programs, such as heating, cooling, constant temperature time, etc., and can execute multiple program settings, and supports advance reservation startup function.

• •Remote monitoring: Using network remote technology to achieve remote control, the test chamber can be monitored at any time, and the current data can be viewed through the user's PC and mobile phone, which improves the convenience of testing. The specific control system of the test chamber will vary depending on the model. Please read the "Sanwood Environmental Test Chamber Manual" carefully before use and comply with the safety operating procedures.

The refrigeration system of the test chamber is a complex and important system. The stability of the refrigeration system is crucial to the accuracy and reliability of the test results.

• •Sanwood Technology has developed a refrigerant hot gas defrosting technology, which effectively melts the frost on the evaporator by injecting high-temperature and high-pressure refrigerant steam into the heat exchanger in the test chamber. This not only ensures that the evaporator does not frost, but also greatly reduces the energy consumption of the equipment.
• •The refrigeration unit adopts an internationally renowned brand.
• •Optimize the layout of the refrigeration system, and adopt VRF (refrigerant flow control) technology based on the PID cold end output principle to achieve low-temperature energy-saving operation, which can reduce energy consumption by 30% under low-temperature conditions.
• •The refrigeration system adopts a modular design, with low failure rate, few welding points, high refrigeration efficiency, good reliability, simple maintenance, and low maintenance cost.
